Hi!
I'm new to Launch Base. My RA2 is EA Origin compiled version, and when I run mods (even unmodified ones), I encountered an error (exe modified by third party, that sort of thing...). Then the Origin window pop up, saying .par file is missing, and the game won't start. (Actually they are not missing!)

But in fact, the game was correctly installed by Origin itself, and running the .exe directly from game directory will start the game and everything works fine. However running from launch Base don't.
